What keeps Eugene Kaspersky up at night?

One of the most worrisome threats in cyber security are independent hackers reverse-engineering potent high-end cyber weapons and espionage tools like Stuxnet, Flame and Gauss, and then unleashing them into the global ecosystem, according to IT security expert Eugene Kaspersky, founder of Kaspersky Lab.

While sophisticated cyberweapons like Stuxnet -- designed to pass benignly through computers until it reached its exact target, the industrial-control systems at Iran's Natanz uranium enrichment facility -- likely cost millions to produce at the hands of state-backed software engineers aided by sophisticated intelligence networks, they are relatively easy to copy once in the wild.
